Repetitive motion or stress injuries affecting the hand and wrist are commonly referred to as Repetitive Strain Injury (RSI) or Cumulative Trauma Disorder (CTD). These conditions are characterized by irritation or damage to tendons, nerves, and other soft tissues due to repetitive motions, forceful exertions, vibrations, or sustained or awkward positions. 

Symptoms

• Persistent or intermittent pain in the hand and wrist.
• Reduced grip strength and dexterity.
• Sensations of numbness, tingling, or burning.
• Inflammation and swelling around affected areas.
• Difficulty in moving the affected hand or wrist.

Causes

Repetitive activities do not automatically cause RSI or CTA.  Reasons an individual may suffer from symptoms of RSI or CTA include:

• Continuous and repetitive hand and wrist movements without adequate rest.
• Excessive force applied during activities.
• Prolonged or awkward positions of the hand and wrist.
• Exposure to vibrations, such as using vibrating tools.

Non-Surgical Treatments:

• Rest is crucial to allow tissues to heal.
• Non-steroidal anti-inflammatory drugs (NSAIDs, topical or oral) may be recommended to manage pain and reduce inflammation.
• Alternating between ice packs and warm compresses can help reduce inflammation.
• Targeted physical therapy exercises to strengthen muscles and improve flexibility.
• Ergonomic modifications to workstations and tools to reduce strain.  

Surgical Treatments

In severe cases, if non-surgical treatments have been unsuccessful, surgical procedures may be considered to relieve pressure on nerves or repair damaged tendons.

Prevention

Performing repetitive tasks with proper form may help prevent strain and injury.

• Maintain proper ergonomics at workstations to reduce strain.
• Take breaks to rest and stretch during repetitive activities.
• Regular exercises to strengthen hand and wrist muscles.
• Ensure proper technique and form during activities.
• Using wrist supports or braces during activities can provide additional support.
